I .8 Claims. (01. 257-124) This invention relates to improvements in heating devices, more particularly to a radiator 'unit designed for heating by convection while at the same time also employing to a limited extentthe principles of conduction and radiation, the object of the invention being to provide a simple, efiicient and inexpensive convection heater for use with steam, hot water; or

vapor. v v A further object of the invention is the provision of a radiator of more ornamental appearance and in which the size is considerably fore, a further object ofthe present invention is the provision of a radiator using cast iron for conducting the heating media and copper. or other highly conductive material for the major part of heating surfacer e In the drawing accompanying andforming a part of this specification Fig. 1 is atop view of this improved convection heating device;

Fig. 2 is a longitudinal sectional side view 7 thereof; V r v t Fig. 3 is an enlarged crosssectional view taken on the line 3-3 of Fig. 2; and I Fig. 4 is a perspective view of one ofthe copper fins used in this convection. heater to radiate the heat. r r

v Similar characters of reference indicate corresponding parts in the several views.

Before explaining in detail the present improvement and mode of operation thereof, I desire to have it understoodthat the invention is not limited to the details of construction and arrangement of parts which are illustrated in the accompanying drawing since the'invention is capable of other embodiments, and that the phraseology which I employ is for the purpose "5Q of description and not of limitation.

The present improvement comprises a cored casting 2 of cast iron or other durable material.

designed to carry the heating media. This casting 2 comprises two or more hollow side secend sections 5 of the same material which serv as manifolds for the side sections 3.

At one end as at. 6 is an:inlet for the steam or other heating media while at the other end is an outlet 7.

Between thesections-3 a plurality of corrug ated:fins of wedgeshaped formation are attached. These'fins are tapered to fit the inner Walls 4. of the sides-3 and are flanged on either side thereof as at v8 to insure thermal, contact withthe sides 4 to .which they may be also attached if necessary by some chemical means such as solder. They may be made of copper or other highly conductive material and are corrugated totake up the expansion and contraction of the metal.

Thesecopper fins areofi very light material and are wedge shaped to securely fit within and between the taperedfaces 4 of the sides 3, the wedge shapeformation thereof serving to prevent their falling through the bottom and also to have a larger surface at theirtops because of the greater expansion of the heated air at that point. The open bottom-.offthe, heater permitsthe air to enter at a temperature of approximately'seventy degrees (70) and'become heated as it rises between-the hot corrugated plates to approximately one hundred and forty degrees (140) -when' it reaches the top of the heater and thus as it rises from the heater and mixes with the air. of the roomit serves to heat the same; -This increased area at the top also serves to decrease the fric-. tion. 3

p The corrugations prevent the thin plates from buckling as they expand upon being heated as would be the case if they were entirely straight and because of their extreme light weight they will readily contract and expand as an accordion rather than buckle.

Between the. sides supporting webs such as, 9 may be placed at intervals'as desired for reinforcing the casing.

While copper is a highly conductive material it has never been proved successful as a radiator because it is soft and not durable, is easily distorted and no data is available on corrosion when in contact with the heating media. In this improved heater the outside casing is entirely of cast iron or some other proved metal while the inside structure is of copper thereby permitting the use of a highly conductive metal for heating purposes and a proved metal for conducting the heating media. The media enters the cast casing2 by means of the inlet 6 passing through the manifold 5 and then around through the two sides 3 to the manifold at the opposite end and thence out through the outlet pipe 7.

The circulation of this heating media through the sides 3 heats the casing by means of convection currents and the copper fins being wedged within the sides 4 gives a good thermal contact thus permitting them to become quickly and easily heated by conduction and they in turn transmit the heated air by convection to the room.

Thus it will be seen that I have constructed a new and highly efiicient convection heating radiator which utilizes metal highly conductive in nature in combination with proved metal which,

will not corrode rapidly in such manner that the heating media never comes in contact with the light material thus preventing corrosion thereof.

The strong outer casing also serves as a protector to this light metal thereby eliminating distor-' tion and because of the high conductivity of the light weight metal a greater amount of effective heat may be'transmitted to the room with less consumption of energy.

In practice some form of light weight material may be used as a cover for the heating device and this cover may be of ornamental design to add to the attractive appearance of the'heating device.

It is to be understood that-by describing in detail herein any particular form, structure, or arrangement, it is not intended to limit the invention beyond the terms of the severalclaims or the requirements of the prior art.
